ipt to 3ds conversion is a matter of export between Autodesk Inventor CAD files (.ipt) and 3ds Max files (.3ds). According Autodesk website, the best way to do this would be to export your file in Inventor to SAT format and import that to 3ds Max.
But it might be possible that some tools allow this directly. Actually 3ds Max 2022 can import IPT/IAM format by default, with a few limitations (animation paths, lightning) that are described on Autodesk website.
